LOW IN STIMULANTS

LONG LASTING ENERGY*

INCREASE PUMP AND STAMINA*

SizeSlim PRE-WORKOUT is designed to increase your energy and performance levels in the gym.*

SizeSlim PRE-WORKOUT provides you with the focus you need to help you get “in-the-zone” and power through your workout without the uncomfortable jitters.*

SizeSlim PRE-WORKOUT features key ingredients to help improve blood flow and provide you with a better “pump” while training. SizeSlim PRE-WORKOUT kicks in fast to increase stamina during exercise and stays with you until your last rep!*

3g
Citrulline Malate 2:1

This amino acid works to improve blood flow and nutrient delivery to the muscle cells during training, enhance nitric oxide production for better pumps, and helps to delay the onset of fatigue during intense training.*

1g
Beta-Alanine

Helps to increase training volume and strength by buffering lactic acid and thus delaying the onset of muscle fatigue.*

1g
Schisandra

This Chinese herb helps fight free radical damage and supports a healthy inflammation response due to exercise.* Schisandra has also been shown to support a healthy hormonal balance in the body, improving our ability to deal with physical and psychological stressors.*

750
Agmatine Sulfate

Works with Citrulline Malate to improve vasodilation which helps to improve muscle pumps. Anecdotal evidence suggests these pumps may help to increase the rate of protein synthesis, allowing for a potential increase in the rate of muscle growth.*

100mg
Norvaline

When your body produces nitric oxide it also produces enzymes that restrict that production. Norvaline works to inhibit Arginase which is produced by the body to inhibit Nitric Oxide production resulting in even better “pumps” and nutrient transportation during and after exercise.*

100mg
Choline Bitartrate

A neurotransmitter found to help improve mental function and energy. Choline Bitartrate as also been shown to aid in the improvement of overall brain health and mental focus by supporting the health of neurons and other brain cells.*

Flavor without sacrifice

clean. simple. delicious.

SizeSlim PRE-WORKOUT is sweetened naturally with STEVIA and is made with only NATURAL FLAVORS to support your healthy lifestyle without sacrificing taste or performance.

Overall, I noticed the powders have an underlying bitterness. Not necessarily a bad thing, it added a depth to some of the flavors that you don't get with most supplement products. Not sure if the bitterness came from the stevia (stevia can sometimes have that flavor) or if the natural flavorings can't cover a bitterness from the ingredients. I did notice that if you used more water, the bitterness decreased considerably, so that's what I recommend. I was using one packet (one scoop?) for about 20 oz water and I barely noticed it. If I went with 12 oz per packet, the bitterness was pretty strong. Energy and pump was mild - this is a PWO I would definitely look to take 2 scoops of! 8/10 Kiwi Strawberry - My favorite flavor out of the two PWO's. Really good. Flavor is natural and the bitterness is minimal (I would still go for more water versus less) Pineapple Orange Punch - Didn't really like this one as much. Reminded me a little of Orange Tang or Sunny-D. Sizeslim is a solid brand with solid products in interesting flavors. If you are concerned with chemicals in your supplements, this is the way to go with the natural flavors and stevia!

I like this pwo because it was not too sweet. I cant drink overly sweet candy flavour drinks but this was really pleasant and its made with stevia too which i always prefer to chemical sweeteners. Kiwi strawberry is best flavour but i like the pineapple orange too. It mixes up super easy a little bit foamy but not too bad. Effect was great...im a bit immune to caffeine but this supp gave me like a calm focused edge. It did take about a hour to work on me

Good energy boost, and loved the focus, but didn't care for the tastes. The kiwi strawberry I expected to be sweet, but turned out kind of bitter. The orange pineapple tasted a little too much like orange peel, and was a little sour/tart because of it. The effects were noticeable a good 15 minutes after drinking it, and I was pleased at the energy after a rough couple nights sleeping. It's naturally flavored, which I know matters for a lot of people, but I wish they would have been a bit sweeter.

I got good energy and endurance with this product, but the taste was a little rough; I had to play around with how much water to add to make it tolerable. Perhaps bumping up the flavor a little would help. Really appreciate the all-natural ingredients and the inclusion of Beta Alanine, Citrulline Malate and a few others which I had never heard of but have interesting profiles, especially those promoting NO production. I would prefer a little more caffeine since I am stim tolerant but overall, a decent pre-workout.

im rather sensitive to stims so i was really happy to see that the caffeine was kept within moderate level in SizeSlim PRE. the pumps and focus are very good and longlasting. the Kiwi Strawberry flavor is nicely done and totally natural favored and sweetened. i though this was well balanced and effective!
